Will SpamAssassin filter out viruses, worms, and trojan horses?
No. SpamAssassin is designed to focus entirely on filtering spam. The task of identifying spam is very complicated and resource intensive. Adding virus detection to SpamAssassin would create an intense demand on system resources, and slow down the filtering process considerably. To avoid long delays in receiving your emails, SpamAssassin is devoted to only filtering for spam. However, our email servers are configured to scan all incoming emails for viruses before they are allowed onto our servers. While it is not possible to filter out every virus that is recieved, we take every possible precaution to limit the amount of virus emails that enter our system. To minimize your risk of contracting a virus, we strongly recomend all of our customers have anti-virus software installed on their computers. Be sure to keep your anti-virus software updated regularly as new viruses are encountered on a daily basis.
